Cobb's Big SF WRX Intake System is purpose built to provide increased airflow to you FA20DIT powered WRX. The dual cone "green" air filter is washable so you can clean and re-use for the life of your car. The mandrel bent, black powder coated 3" aluminum tubing was engineered by Cobb to improve pre-turbo air flow. The Cobb designed aluminum airbox helps to keep heat soak at bay and uses the Subaru under-hood air snorkel all while keeping your engine bay looking sharp.
